STATUS_SXS_FILE_NOT_PART_OF_ASSEMBLY

The file is outside the declared assembly membership

STATUS_SXS_FILE_NOT_PART_OF_ASSEMBLY means that an operation referred to a file that the relevant assembly manifest does not declare as one of its members. The physical file may exist on disk; the failure concerns membership in the manifest-defined assembly.

This differs from STATUS_SXS_ASSEMBLY_NOT_FOUND, where the assembly identity cannot be resolved, and from STATUS_SXS_FILE_HASH_MISMATCH, where a declared file is present but its verification data does not match. Adding an untracked file to an installation directory does not make it an assembly member.

What to inspect

Compare the exact filename and relative location with the file entries in the selected assembly manifest.
Verify which assembly identity was resolved; a file can belong to a different side-by-side assembly with a similar name.
Regenerate the manifest from the packaging source rather than editing the installed assembly membership by hand.
